Personally, I think unless you are using crap thick undiluted screenwasher, it's nothing to do with it.

I had one go ages ago and I ordered a genuine one from Toyota, not that expensive, but I do remember the parts guy not denying its unusual !!

Easy to order and easy to replace, I just had to pull back a bit of the under bonnet insulation, a ten minute job.
